Not sure if its nationwide but the co-op i work in (kilmacolm) has:
Luis Felipe Edwards wine (white, rose & red) reduced to £3. Red is flying off the shelves.
Champagne (£13 one) £9.
Marques de monstrol rose cava £4.
Theres another champagne down to £7, another cava £4 and another couple of wines down to £3 & £4. Sorry i cant remember all the names.
Thinks its all the xmas stock.
